NIGHT-LAM P.

SPECIFICATION .forming part of Letters Patent No. 641,749, dated January23, 1900. Application led May 3, 1829. Serial No. 715,457. (No model.)

.To all whom, it may concern.-

Be it known that I, GEORGE ARBUTHNOTT SMITH, a subject of Her Majestythe Queen of Great Britain, residing at Alberni, county of Vancouver,Province of British Columbia, Canada, have invented certain new anduseful Improvements in Night-Lamps; and I do hereby declare that thefollowing isa full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to lamp-burners; and it has for its object toprovide an attachment for lamp-burners which will permit an ordinarylamp to be used as a night-lamp.

A further object is to provide an ordinary lamp with an attachmentwhereby it may be readily converted into a night-lamp the constructionof which is simple and inexpensive, consists of few parts, and which maybe readily and safely operated.

To these ends the invention consists in a night-lamp attachment forlamps constructed substantially as hereinafter illustrated anddescribed, and defined in the appended claims.

In the drawings, in which similar letters of reference refer to similarparts, Figure l is a vertical central section of an ordinary form oflamp provided with the improved nightlamp attachment, and Fig. 2represents a perspective view of a detail of the construction.

In the drawings, A represents a lamp of any ordinary or preferred form,which is provided with the usual reservoir, base, and burner andprovided with a round wick.

The standard A of the lamp is formed hollow and is provided with atubular extension d, preferably integral therewith, which projects up toa level with the burner.

The circular wick B is slidably mounted upon the tubular extension d,and to' the lower portion of said wick is fixed the metal band d',having an operating-rod B', which projects upwardly through the upperside of the reservoir in convenient position to be grasped by the hands.By means of this construction the Wick is adapted to be properly adjusted as required, though, of course, it is to be understood that theordinary means foradjusting the wick may be employed, if preferred.

In the lower portion of the standard A are fixed two partitions c2 d3,which are perforated to receive and guide the rod C, the lower end Vofwhich is bent at right angles and extends outwardly through a slot d4 inthe side of the standard, where it forms a handle, by means of which thesaid -rod may be given a vertical movement. The slot d4 is provided withan offset, whereby the handle may be engaged to lock the rod in itslower or retracted position. A suitable spring a5 is sleeved upon saidrod C and is fixed at its upper end to the said rod, while the lower endbears against the partition as, whereby the said rod is normally held inits upper or raised position.

To the upper end of the rod O, which projects some distance above theburner, is revolubly mounted, by means of a cross-rod d, the cap D,formed of a short tubular body portion d, which tits closely within thetubular extension d and is adapted to slide there in when actuated bythe rod C. The upper portion of the cap D is provided with an annularflange d2, which is preferably angular, as shown, and which projectsover the edge of the wick and is adapted to be forced down upon the topof said wick by the downward movement of the rod C. A portion of theflange d2 of the cap D is cut away or perforated at da, leaving aportion of the wick exposed or free from contact with the said flangewhen the cap is lowered upon the wick.

It will be readily understood from the above description that when theparts are in the position shown in Fig. 1 of the drawings the wick canbe lighted and the lamp used as an ordinary lamp. When it is desired tohave a dim light, as when the lamp is to be used as a night-lamp, thecap D is forced down upon the wick by means of the rod C, and the flameof the wick is extinguished, with the exception of the small portionuncovered by reason of the opening or perforation d3 `in the flange ofthe cap D. This opening may be made of any desirable size best suitedfor the purpose, it being only necessary to leave enough of the wickexposed to provide a dim light.

The cap D, being revolubly connected to the rod C, can be freely turnedin the tubular extension a by means of a suitable handle d4, formed onsaid cap, so as to cause the cut- IOO away portion of the `lian ge cl2to expose a fresh portion of the wick when necessary by reason of theburning away of the wick beneath said cut-away portion. Thus the wickwill be prevented from being unevenly consumed, as would be the casewere the same portion of the wick always exposed through the cutawayportion.

By means of this construction an ordinary lamp may be used as anight-lamp without danger and with great economy in the amount of oilconsumed and without the disagreeable odor and smoke caused by turninglow the wick of an ordinary lamp.

While I have herein shown a preferred form of carrying my invention intoeffect, yet I do not desire to limit myself to such preferred details ofconstruction, but claim the right to use any and all modificationsthereof which will serve to carry into effect the objects to be attainedby this invention in so far as such modifications and changes may fallwithin the spirit and scope of my said invention.

I claiml. An attachment for lamps, comprising a tubular extensionadapted to support the wick, a rotatable cap slidably mounted in the topof said extension and adapted to cover all but a portion of said wick,and means for lowering and holding said cap upon the wick, substantiallyas described.

2. An attachmentfor lamps, comprising a tubular extension adapted tosupport the wick, a rotatable cap slidably mounted in the top of saidextension, a flange integral with said cap and having a perforation, andmeans for lowering and holding said cap upon the wick, substantially asdescribed.

3. An attachment for lamps, comprising a tubular extension adapted tosupport the wick, a rotatable cap slidably mounted in the top of saidextension, a flange integral with said cap and provided with aperforation, a spring-pressed rod connected with said cap and providedwith an operating-handle, and means for locking the said rod in itsretracted position, substantially as described.

4. The combination with a lamp provided with the usual burner, reservoirand stand-4 ard, of an attachment therefor, comprisinga tubularextension integral with the standard and connected at its upper end withthe burner, a wick slidably mounted on said tubular extension, means foradjusting said Wick, a rotatable cap slidably mounted in the top of saidextension, a fiange integral with said cap and provided with aperforation, a spring-pressed rod connected with said cap and extendingdownwardly through said extension and provided with an operating-handle,and means for locking said rod in its retracted position, substantiallyas described. In witness whereof I have hereunto set my hand in thepresence of two witnesses.
